Halo Shield – Patent Pending – GB2007899.4
How To Clean The Face Shield
The Halo Face Shield should be disengaged from the hook and loop pad to enable cleaning.
• Users should follow their own guidance procedures for cleaning and sterilisation subject to testing the cleaning solution of your choice on your own Halo Shield to protect the clarity and visibility of the Halo Shield.
• It is advised to you check your chosen cleaning solution on the Halo Shield visor, in a small, inconspicuous corner before carrying out the cleaning operation on the whole Halo Shield.
• We have produced a slideshow below demonstrating a cleaning method. We have used a industry standard cleaning wipe which are used in our factory environment.
• Storage of Halo Shield ‐ We recommend the construction operative takes Halo Shield off when work has finished and place the Halo Shield ina air tight freezer bag until ready to use the following day.

PU & TPU?
Thermoplastic polyurethane, also referred to as PU & TPU, is a flexible film that can be use on personal protective face shield equipment with high elongation and properties and characteristics that are superior to most polyolefinic films. Thus TPU is often an excellent choice for more demanding film applications such as equipment ppe. This thermoplastic is inherently strong, flexible, tough and easy to work with, and unlike vinyl, it is free of plasticizers, and thus won’t become brittle or lose performance over time on a face shield. TPU film also exhibits excellent dynamic flex performance, abrasion resistance and tear strength to provide effective protection with social distancing on this face shield. Used in combination with face masks to protect eyes nose and mouth when leaving home.
TPUs have excellent resistance to grease and pure mineral oils such as lubricants and fuel, and exhibit outstanding resistance to hydrolysis. In particular, polyether-based grades will not undergo any noticeable decomposition when exposed to hot steam and the mechanical properties are nearly unchanged whereas ester-based grades can be somewhat susceptible to hydrolysis at elevated temperatures. The polyether based TPU’s also exhibit excellent resistance to microbiological attack whereas ester-based grades can withstand higher temperatures, and used on face shield.
TPUs are easy to work with, and can be easily modified to suit a particular application through the addition of fillers, dyes, lubricants, stabilizers and other additives.
TPU films are well suited for many demanding industrial applications. Due to the low odour, high chemical resistance and inertness, many TPU grades are suitable for packaging applications under FDA regulations.
TPU films can be used over a wide range of temperatures. For example, common ester-based grades can withstand temperatures up to 130°C, whereas many ether-based grades can withstand temperatures up to 90°C.
TPU films are sold in various types, thicknesses, widths with properties tailored to meet specific requirements of particular end uses.
